Description

Technical Field

[0001] This utility model relates to the field of refrigerators, and more particularly to a cross-door air-cooled refrigerator. Background Technology

[0002] The principle of a frost-free refrigerator is to use air for cooling. When hot air flows through the built-in evaporator, heat exchange occurs directly between the two due to the high air temperature and the low evaporator temperature, causing the air temperature to drop. Since frost-free refrigerators use air for cooling, it can be understood that there is a continuous circulation of cold air inside the refrigerator to keep food fresh. Therefore, the airtightness of the refrigerator is particularly important. The location in the refrigerator where the door contacts the inner liner is where sealing defects may occur. The common sealing method is simply to place a sealing strip at the contact point between the refrigerator door and the inner liner. Relying on the sealing strip, however, the sealing strip will age after a long period of use, which will lead to a deterioration of the airtightness inside the frost-free refrigerator and affect the cooling effect. In view of this, we designed a cross-door frost-free refrigerator. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a cross-door air-cooled refrigerator, which can effectively solve the problem that the sealing method of the existing air-cooled refrigerator is only set by a sealing strip at the contact position between the refrigerator door and the refrigerator liner. It relies on the sealing strip for sealing, but after a long period of use, the sealing strip will age, which will lead to poor sealing inside the air-cooled refrigerator and affect the cooling effect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A cross-door air-cooled refrigerator includes a cabinet and a plurality of doors movably connected to the front side of the cabinet; A sealing strip is movably connected inside the box door. When the box door is closed, the outer wall of the sealing strip overlaps with the outside of the box body. A movable plate is movably connected inside the box door. The movable plate is fixedly connected to the sealing strip, and the ends of the sealing strips on two adjacent box doors remain overlapping.

[0005] Preferably, the box body has two storage cavities with a symmetrical upper and lower structure, and two overlapping plates are fixedly connected to the outer surface of the box body with a symmetrical upper and lower structure. The inner end of the box door is fixedly connected to a rotating shaft, and the rotating shaft is rotatably connected to the overlapping plates.

[0006] Preferably, the door has a U-shaped groove, and the sealing strip slides into the U-shaped groove. When the door is closed, the outer wall of the sealing strip overlaps with the outer wall of the box.

[0007] Preferably, the movable plate is elastically connected to the inner wall of the door via an elastic ring, and the elastic ring has a cavity, and the movable plate also includes a chamber formed within the sealing strip. The cavity is connected to the chamber within the sealing strip via a connecting hole.

[0008] Preferably, it further includes a movable plate movably connected to the inside of the door, the movable plate having a first inclined surface, and a fixed plate fixedly connected to the outer wall of one side of the movable plate, the outer wall of the fixed plate having a second inclined surface, the second inclined surface and the first inclined surface being slidably engaged.

[0009] Preferably, it also includes a magnetic strip fixedly installed at the end of the movable plate, the magnetic strips on the two adjacent boxes being magnetically attracted, and an elastic membrane fixedly installed on the outer wall of the box door, the two magnetic strips being magnetically attracted when the two adjacent boxes are in a closed state, so that the two adjacent elastic membranes are in close contact.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a movable plate installed inside the refrigerator door. When the door is closed, the sliding fit between the inclined surfaces allows the movable plate and the sealing strip to effectively seal the interior of the refrigerator. Furthermore, the magnetic attraction between the magnetic strips inside adjacent doors also ensures the sealing of the door connection points. Attached Figure Description

Example

[0018] See attached document Figures 1-5As shown, a cross-door air-cooled refrigerator includes a cabinet 100 and multiple doors 200 movably connected to the front of the cabinet 100. A sealing strip 310 is movably connected inside the door 200. When the door 200 is closed, the outer wall of the sealing strip 310 overlaps with the outside of the cabinet 100. The cabinet 100 has two storage cavities 101 with a symmetrical structure. Two overlapping plates 110 are fixedly connected to the outer surface of the cabinet 100 with a symmetrical structure on both sides. A rotating shaft 210 is fixedly connected to the inner end of the door 200. The rotating shaft 210 is rotatably connected to the overlapping plate 110. Specifically, in this application, the door 200 is rotatably connected to the body 100, the corresponding overlapping plate 110 is located in the middle of the body 100, and the storage cavity 101 is provided with two symmetrical structures. When the door 200 is closed, the sealing strip 310 on the corresponding door 200 will overlap with the outer wall of the body 100, thereby achieving effective sealing of the storage cavity 101.

[0019] Furthermore, to ensure a tight fit between the door 200 and the enclosure 100 when closed, and to guarantee the airtightness of the storage cavity 101, a movable plate 300 is movably connected inside the door 200. The movable plate 300 is fixedly connected to the sealing strip 310, and the ends of the sealing strips 310 on adjacent doors 200 overlap. When two doors 200 at the same level are closed, the ends of the corresponding sealing strips 310 are in contact. The sealing strips 310 are U-shaped, and the openings of the sealing strips 310 inside the two doors 200 are corresponding. When the doors 200 are closed, the ends of the corresponding sealing strips 310 will contact each other, thus forming a relatively complete ring structure to achieve a complete seal of the storage cavity 101.

[0020] Furthermore, to ensure stable contact between the sealing strip 310 and the outer wall of the housing 100, a U-shaped groove 201 is provided inside the door 200 in this application. The sealing strip 310 slides in the U-shaped groove 201, and when the door 200 is closed, the outer wall of the sealing strip 310 overlaps with the outer wall of the housing 100. It also includes a movable plate 400 movably connected to the inside of the door 200, with a first inclined surface 401 on the movable plate 400. It further includes a fixed plate 320 fixedly connected to one side of the outer wall of the movable plate 300, with a second inclined surface 321 on the outer wall of the fixed plate 320. The second inclined surface 321 slides in contact with the first inclined surface 401. Finally, it includes a magnetic strip 410 fixedly installed at the end of the movable plate 400, with the magnetic strips 410 on adjacent doors 200 magnetically attracted.

[0021] Specifically, in this application, when the cabinet door 200 is in the closed state, the magnetic strips 410 inside the two cabinet doors 200 at the same horizontal position will be magnetically attracted to each other. At this time, the movable plate 400 will slide inside the cabinet door 200. The first inclined surface 401 will slide relative to the second inclined surface 321, and drive the movable plate 300 to adjust its position towards one side of the cabinet 100, thereby ensuring the elastic contact between the sealing strip 310 and the outer wall of the cabinet 100. In this way, the sealing performance inside the storage cavity 101 is further guaranteed.

[0022] Furthermore, it also includes an elastic membrane 420 fixedly installed on the outer wall of the door 200. When two adjacent doors 200 are closed, the corresponding two magnetic strips 410 are magnetically attracted, making the two adjacent elastic membranes 420 in close contact. When two doors 200 located at the same horizontal position are closed, the corresponding two magnetic strips 410 will maintain a magnetic attraction relationship. At this time, the two different elastic membranes 420 will also maintain a tight overlap relationship. In this way, the sealing of the connection is guaranteed when the door 200 is closed.

[0023] Specifically, in this application, the movable plate 300 is elastically connected to the inner wall of the cabinet door 200 via an elastic ring 330, and the elastic ring 330 has a cavity 331, which also includes a chamber within the sealing strip 310. The cavity 331 is connected to the chamber within the sealing strip 310 via a connecting hole. When the movable plate 400 moves, the corresponding movable plate 300 will move, and the corresponding elastic ring 330 will be compressed. Consequently, the cavity 331 within the elastic ring 330 will be compressed. Combined with the communication between the cavity 331 and the chamber, after the gas in the cavity 331 enters the chamber, it will squeeze the sealing strip 310 towards the side closer to the cabinet 100, thereby effectively sealing the storage cavity 101.

[0024] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
